Use, which measures the perceived actual use of an employee portal by a company’s staff. To assess use in this context, we propose measuring the perceived length of time that the different functionalities, such as retrieving and publishing information, communicating, collaboration, networking, and executing work processes, are used. Since we assume that portal use is non-mandatory (Tojib et al., 2008), we believe that perceived use is a sufficient indicator. Thus, we do not measure the intention to use the portal as a surrogate for portal use.
